Continuous stationery guide means

ABSTRACT

Guide means for attachment to a typewriter so that continuous stationery can be guided to the platen of the typewriter comprises a backing plate which is adapted to be secured to the typewriter and a guide plate pivotally secured to the backing plate. The guide plate has a throat through which continuous stationery passes to the typewriter. The guide plate is pivoted upwardly, so that the leading edge of the continuous stationery is lifted from the platen, when it is required to type an additional letters and envelopes.

Continuous stationery web feed devices have been provided embodying guides whereby continuous stationery is fed to and around the platen of a typewriter and such devices have been found to be suitable for accurately feeding the continuous stationery around the platen. However, it is necessary to load the continuous stationery webs into such feed devices and if it is required during the processing of such continuous stationery that the typist shall type a letter on for example plain headed note-paper an unproductive amount of time is spent in unloading and reloading continuous stationery into the typewriter.

It is an object of the present invention to provide an improved construction of guide means for continuous stationery being fed to a typewriter.

It is a further. object of the invention to provide an improved construction of continuous stationery guide means which will enable a continuous web to be retained by the guide means when the typewriter is required for other purposes.

According to the present invention there is provided guide means for guiding a continuous stationery web to a typewriter comprising a backing plate adapted to be secured at the infeed of a typewriter and a guide plate pivoted to the backing plate, said guide plate having side guide members and a pair of transverse guide members, the guide plate being arranged so that in one position of the guide plate continuous stationery can pass between the side guide members and the transverse guide members to the throat of the typewriter and in a pivoted position of the guide plate, the continuous stationery is swung out of a feed path of stationery to the typewriter.

One embodiment of the present invention will now be described by way of example with reference to the accompanying drawing in which:

FIG. 1. is a perspective view of guide means affixed to a typewriter.

FIG. 2. is a sectional side view of the guide means.

The guide means comprises a backing plate 1 and a guide plate, generally designated 7. The backing plate 1 is secured to a throat plate 2 of a typewriter T by means of screws 3 and extends upwardly from the throat plate 2 at a slight angle so as to be inclined upwardly and rearwardly from the rear of the typewriter. The upper end of the backing plate 1 is turned to form an inwardly curved lip 4. Extending upwardly and rearwardly from the upper sides of the backing plate 1 are ears 5, each formed with a respective aperture 6.

The guide plate 7 comprises a base plate 8, a front plate 9 and side plates or blades 10, each having a projection 11, the projections 11 being received in the apertures 6 of the ears so that the guide plate 7 is pivotally mounted on the backing plate 1. The base plate 8 is flat but the front plate 9 has a trailing part 9A which is inclined to the backing plate 8 to facilitate insertion of the leading edge of continuous stationery between the base plate 8 and the front plate 9. The leading part 98 of the front plate 9 is V-shaped and is parallel to the backing plate 1. The guide plate 7 is pivotally movable about the pivot means 6, 11 between the position shown in full lines in FIG. 2 and the position shown in dotted lines in FIG. 2. That is to say, in one position continuous stationery is guided to the throat of the typewriter, and in the other position the continuous stationery is retained out of the path of paper stationery fed into the typewriter.

When it is required to feed a continuous stationery web 14 into the typewriter T, the plate 7 is located in the position shown in full lines in FIGS. 1 and 2. The leading edge of the continuous stationery web 14 is then fed from a pack (not shown) over the curved lip 4 and between the base plate 8 and the front plate 9 to the throat of the typewriter T. It is then passed under and around part of the platen 15 of the typewriter T so that typing can be effected. It will, of course, be understood that the continuous web 14 is fed forwardly by rotation of the platen 15 in the usual way. When it is required to detach a form length of the continuous stationery 14, a

form length is fed out of the typewriter T and a form length is detached by tearing across cross perforations in the continuous stationery web 14.

If it is required to type a letter separate from the continuous stationery web 14, the guide plate 7 is swung about the pivot 6, 11 to the position shown in dotted lines in FIG. 2 in which position the continuous stationery web 14 is removed from the platen l5 and does not obstruct the additional typing operation, during which an appropriate record sheet may be fed along the then exposed smooth surface of the backing plate 1.

What we claim is:

1. In a typewriter having a conventional supporting frame and platen, and means for guiding stationery toward said platen, said guiding means comprising an upwardly and rearwardly inclined smooth backing plate rigidly secured to said frame adjacent the infeed of the platen and along which stationery may be guided to the platen, a supplemental guide plate alternatively usable to guide an alternative type of stationery along its upper outer surface and in use disposable in an upwardly and rearwardly inclined position overlying and substantially in contact with the smooth surface of said backing plate, means for pivoting said guide plate to said backing plate for swinging movement to and from operative position, said pivoting means comprising cooperating pivot elements consisting of projecting pivot pins and openings to receive them, one of such elements carried by the upward rearward end portion of said backing plate and the other carried by the adjacent upward rearward portion of the guide plate; said backing plate being provided with spaced upstanding ears and the guide plate being provided with spaced stationery-confining and guiding side plates, the said side plates and ears comprising the said adjacent upward and rearward end portions of the guide and backing plates which carry the respective pivot elements; and a front plate carried by and spaced from said guide plate to form a mouth through which the said alternative type of stationery may be fed.
